Abstract
L'invention concerne une composition de revêtement de bois comprenant : une résine acrylique ou polyuréthane ou alkid, ou une combinaison de celles-ci ; un solvant à base d'eau comprenant de l'eau et un polyalcool, ou un solvant organique choisi parmi les cétones, les esters, les hydrocarbures aromatiques en tant que toluène, seuls ou en combinaison ; la résine ayant un rapport massique fixé entre 10 % et 80 % ou entre 20 % et 70 %, respectivement avec un ou l'autre type de solvant. Les compositions comprennent un additif de protection contre les UV comprenant des polyphénols, en particulier un mélange de tanins extraits d'un bois tel que le bois de Fagacée, de Mimosaceae ou de Rosacée, à un rapport massique fixé entre 0,5 % et 4 % du poids de la composition. L'exigence essentielle de l'additif de protection contre les UV, à savoir fonctionner dans une composition contenant un solvant à base d'eau, est que le pH soit supérieur à une valeur minimale prédéterminée supérieure à 7, qui peut être éventuellement fournie par la résine anionique ou non ionique elle-même, ou par une quantité appropriée d'un modificateur de pH alcalin. Des mélanges de polyphénols extraits de bois se sont avérés plus efficaces contre les radicaux libres induits par les UV dans des compositions à base de solvant organique. L'invention fournit une solution plus économique contre les effets des UV sur des éléments en bois que les composés couramment utilisés en tant qu'additifs dans le même but.
